Abstract
The invention relates to a control system for a tufting machine configured for forming tufted carpet. The tufting machine can have a system controller in communication with the tufting machine and with a plurality of yarn feed controllers for controlling operation of yarn feed motors that are configured to supply yarn from a source of yarn to the tufting machine. The system controller is programmable to enable input of a plurality of predetermined yarn feed profiles for selected stitches of a programmed pattern to be tufted such that, although at least two of the predetermined yarn feed profiles can be different, substantially the same feed length of yarn is used from each of the plurality of yarns.
